The first step in the scientific method
Observation
If you take an object and cut it into smaller pieces what is true about the densities of the smaller pieces?
The density of the smaller pieces are the same as the larger piece.
Distance only has a magnitude(size) so it is a ______ quantity
scalar

If you increase the volume of an object but keep the mass the same what happens to its density?
density goes down
If a person walks 2 miles to the right and then 3 miles to the left what is their displacement?

Zero
If a portion of a distance vs. time graph is horizontal what is true about that horizontal portion.
The object is not moving during that time.
